Navarro–Frenk–White profile. The Navarro–Frenk–White (NFW) profile is a spatial mass distribution of dark matter fitted to dark matter halos identified in N-body simulations by Julio Navarro, Carlos Frenk and Simon White. [ 1] The NFW profile is one of the most commonly used model profiles for dark matter halos. [ 2]
The factor of 1 / 2 is present because the zero-point energy of the n th mode is 1 / 2 E n, where E n is the energy increment for the n th mode. (It is the same 1 / 2 as appears in the equation E = 1 / 2 ħω.) Written in this way, this sum is clearly divergent; however, it can be used to create finite expressions.
Macroeconomics. In economics, stagflation (or recession-inflation) is a situation in which the inflation rate is high or increasing, the economic growth rate slows, and unemployment remains steadily high. Stagflation, once thought impossible, [ 1] poses a dilemma for economic policy, as measures to reduce inflation may exacerbate unemployment.
For example, if the heights of two lines are found to be h 1 and h 2, c 1 = h 1 / ε 1 and c 2 = h 2 / ε 2. [13] Parameters of the line shape are unknown. The intensity of each component is a function of at least 3 parameters, position, height and half-width. In addition one or both of the line shape function and baseline function may not be ...
As of Friday, FanGraphs postseason odds had 15 contenders with relatively robust odds — nearly 40% or better. Eight other clubs were below 1% (six of them actually at 0%). That leaves seven long ...
The hypothesis of dark matter has an elaborate history. [18] In the appendices of the book Baltimore lectures on molecular dynamics and the wave theory of light where the main text was based on a series of lectures given in 1884, [19] Lord Kelvin discussed the potential number of stars around the Sun from the observed velocity dispersion of the stars near the Sun, assuming that the Sun was 20 ...
From fiscal 2020 to 2024, Nike Direct's revenue rose at a CAGR of 15% as its wholesale revenue only increased at a CAGR of 5%. Nike generated 42% of its sales from Nike Direct in fiscal 2024 ...
Thermodynamic temperature is a quantity defined in thermodynamics as distinct from kinetic theory or statistical mechanics.. Historically, thermodynamic temperature was defined by Lord Kelvin in terms of a macroscopic relation between thermodynamic work and heat transfer as defined in thermodynamics, but the kelvin was redefined by international agreement in 2019 in terms of phenomena that are ...
